Duchess Kate switches things up with Gucci minidress

After a steady flow of Alexander McQueen dresses over the last couple of weeks, Duchess Kate has changed things up on Thursday.

She appeared at the opening of a new exhibit at London's Victoria & Albert Museum in a tweed Gucci minidress accented with the Italian fashion house's trademark two-tone ribbon detailing and pearl buttons.

She finished the look with a red suede clutch and navy block heels. And she even let her hair back down, going with a half-updo after wearing it up and covering it with hats for her last two major events, Trooping the Colour and Royal Ascot.

And because tweed is about an opaque a fabric as they come, she didn't have to worry about another Princess Diana moment where her legs were visible due to backlighting.
